IMPROVEMENT IN KITCHEN-VENTILATORS.

Specin'cation forming part of Letters Patent No. 189,114, dated April 3,1877; application tiled May 18, 1876.

To all whom it may concern:

Be it known that I, JAMES A. LEEPER, of Concord, in the county ofCallaway and State of Missouri, have invented certain new and usefulImprovements in Kitchen-ventilators', and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertaius to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to that class of Ventilators that consist,essentially, of a box or case provided with suitable doors or openingsand a Ventilating pipe or iiue, and so constructed that it may be placedover a cooking` stove or range, for the purpose of carrying oi" the heatand odor; and my improvement consists in constructing the Ventilatingbox or case with a double or branched pipe, one branch of which servesas a Ventilating-Hue, while the other forms, when my ventilator is inuse, a section of the stove-pipe that passes into the chimney or out inthe open air.

In the drawing, Figure 1 is a perspective view, and Fig. 2 is a sideelevation.

Similar letters of reference indicate correspondin'g parts in both thefigures.

, A is a box or case, made of wood or similar non-conducting material,and having the closed top or roof D, side doors'B, and legs C. By thelatter it is lifted some distance from the floor, so that the cold airmay readily pass into lthe box, even when the doors B are shut. E and Fare pipes, one of which, F, passes vertically through the roof D, whilethe other, E, passes in a slanting or oblique direction from pipe vFdown into the box.

.When it is desired to use my .ventilator it is simply placed over thecooking-stove, as represented in Fig. 2, and a section of thestove-pipeA is removed, the remaining lower section being conducted intolue F. Another section of pipe, leading into the chimney or out in theopen air, is next affixed upon pipe F, so that this pipe, which is apart of my ventilator, will, for the time being, form a sectionl of thestove-pipe, the corresponding portion of ilue having been removed. Thiscreates a draft through pipe F, and also through the branch pipe E, bywhich, through the last-named pipe, the heat and odor incident tocooking is carried oft' into the tlue.

I am well aware that it is not new to construct a Ventilating-case witha Ventilatingflue and an opening for Ithe stove-pipe to pass through 5but this I do not claim. I am not aware, however, of such a case everhaving been constructed with a branch pipe, E F, one branch of which,when the ventilator is in use, forms a section of the stove-pipe, whilethe other is a iiue for carrying oi' heat and noxious odors, andconducting them into the chimney.

Having thus described my improvement, I claim and desire to secure byvLetters Patent of the United States- The portable Ventilating box orenvelope A, to be placed over a cooking stove or range, and having thedoors B and branch pipe E, connectedV with the main pipe F,substantially as set forth and described.

In testimony that I claim the foregoing as my own I have axed mysignature in presence of two witnesses.

JAMES A. LEEPER.
